Hi
I am running a Mac OS Mojave VM. This does not support the VIRTIO driver, I am stuck with the poor performance of vmx3net interface for accessing data on the host .
So I want to take advantage of my 3x NICS.
- 1x NIC 1Gbe to give Internet to the host (and the VM), and provide web interface to proxmox ; that's easiliy done, I just need to change the vmbr0 bridge_ports line to match the Ethernet Interface that I want to use (on my config, IP is 192.168.1.46, and NIC is enp133s0)
- 1x NIC 10Gbe for the MacOs VM as PCI PassThrough, so that MacOS has a private 10Gbe interface to use when talking to the host, on a separate network (192.167.12 is my manually assigned static address for the MacOs guest ; the PCI device that is sent pass-through is enp14s0f1)
- 1x NIC 10Gbe to use on the Host as an extra private Interface, to communicate with the MacOs VM on the separate network (192.167.1.46 is my manually assigned static address for the host)
This setup works ! Even without using a 10Gbe switch (which I don't have) : I use a direct cable between the two 10Gbe NICs.
Is this the proper way to do it? (one downside is that the MacOs guest must connect twice to the host : one on it's physical 10Gbe device, the other one using a
virtualized vmx3net interface).
Here is /etc/network/interfaces version 1 (working but not elegant):
I tried to use a bridge to bring together the 10Gbe and the 1Gbe NICs handled by the host (enp14s0f0 and enp133s0), but I could not figure out how to make it respond to both "public" address 192.168.1.46 and "private" adress 192.167.1.46
How can I use a bridge that will make it possible for the MacOs VM guest to connect to the Host with only its 10Gb/s passthrough NIC, and be able both to access Internet and the Host, using a single interface ?
thanks !

AppleVirtIO.kext attaches to the VirtIO device, but it doesn't turn it into a usable Interface.
Hiding AppleVirtIO.kext does make it possible to load the manually installed virtio-net.kext, which does turn into an Interface… but that's unable to get plugged in)
Using vmx3net works, but the throughput is 1Gb/s (+-110MB/s).
I can't use virtio-fs as it has no support yet on Mac.
I can't use a block-device such as a whole disk because I need host and guest to be able to modify the shared folder.
